| 摘 要： | 为了在15视场角范围内获得工作谱段范围在400 nm~ 900 nm声光可调谐滤波器(AOTF)成像光谱仪系统的二维空间信息以及一维光谱信息，设计了一种应用于AOTF 成像光谱仪的光学系统。介绍AOTF的工作原理，根据AOTF 成像光谱仪总体方案，对前置系统及后置成像系统进行了设计。设计中前置系统采用倒置的伽利略望远镜结构，后置成像系统采用改进的库克三片式结构。最终完成了一个焦距为19.311 mm，F数为12.3，在34 lp/ mm 的空间频率下各视场调制传递函数( MTF) 均值大于0.5的光学系统。

| Abstract: | In order to obtain the two-dimensional spatial information and one-dimensional spectral information within the field of view (FOV) range of 15 from 400 nm to 900 nm, a kind of system for acousto-optic tunable filter (AOTF) imaging spectrometer was designed. The working principle of AOTF was described. According to the overall plan, the fore-optics and post imaging system were finished. The fore-optic system was utilized the inverted Galileo telescope, and the post had an improved-Cooke triplet-structure. Finally the optic system was completed. The focal length is 19.311 mm and the F number is 12.3. While the spatial frequency is 34 lp/mm, the modulation transfer function (MTF) is 0.5. |
